they dont it stays the same every day
The number of sunspots increases then decreases in a fairly regular cycle, although it's not totally reliable. The time between each maximum or minimum is usually 11 years. I'm not sure if you mean how do individual spots change, but I've just given this answer about groups of sunspots.
because it uses up more of its gases so it cools down more
The number of sunspots on the Sun varies over an 11-year solar cycle. During periods of high solar activity, there can be hundreds of sunspots visible on the Sun's surface. The next peak in sunspot activity is expected around 2025-2026.
All the stars and the Sun are moving through space in different directions and at different speeds. Over long times (to a person) they change their positions in the sky and the constellations change.

No, passport numbers do not change over time. Once a passport is issued, the number remains the same for the duration of its validity.
The Suns activity varies over time including the number of sun spots. they follow an 11 year cycle of relative activity and dormancy. At any one time there may be hundreds of them across the surface.
